Issue Description

When this issue occurs, the laser head won't go back to the home position properly.

You may see the X-axis gantry keeps crashing into the structure of the machine or simply won't move on the Y-axis.

If the machine is connected with XCS in the meantime, you may see a pop-up notification like below.

#2 Check the X-axis gantry

1. If the X-axis gantry is not square, the Y-axis limit switch can't detect the limit piece.
2. Push the X-axis gantry towards the rear plate until it touches it.
3. Then Push it hard against the rear plate so that both ends are aligned.

#4 Check the Installation of the Port and the Sensor

Note: The Y-axis limit switch is in the right corner of the machine near the rear plate.

• Unplug and replug the cable to make sure it is fitted properly.
• Check the black sensor probes for deformation. If it's deformed, please straighten it.

#5 Check the Y-axis limit switch

Note: The Y-axis limit switch is in the right corner of the machine near the rear plate.

1. Manually move the gantry towards the front plate.
2. Insert a black material into the gap between the two sensor probes as shown below, and observe whether the indicator of the Y-axis homing signal changes.

• If it does not change, it indicates the switch is faulty and needs to be replaced.
• If it changes, it means the switch functions properly. Please move on to the next steps.

#6 Check the Cable or the Motor

If none of the above works

If the issue persists, please collect the work log, a picture of the Serial Number sticker on the machine, and the video about the issue, and contact xTool tech support for further advice at: support@xtool.com
